Tw freezing = bad oc?

Hey guys, I was running 1.782GHz for a while but I would get touch wiz freezing on me from time to time.
Do you guys think this is oc related?
I just reverted to one step lower than that, whatever it was.
Hopefully that fixes it.
I'm running sky ics rom and cymbaline kernel. Using an oc script.
Thanks!

It could be the voltage settings. If its not getting enough juice it can start to stall and worse case reboot. If you can rule that out it could also be GPU clocks if they're clocked too high.

I find that our skyrockets don't do well with mix and matching kernels and roms that haven't been tweaked to work together. You may want to try embryo 4.1 if using mohan's kernel. He write both and the integration is almost flawless, and the rom is a touchwiz base which helps our finicky skyrocket with stability. What do you need the overclock for?

I really don't need the oc. I just wanted at least an oc since I love overclocking lol.
If I get any more problems with volts/oc ill see if I can edit the oc script to give more volts.
Thanks guys.
No problems thus far

fair enough, I don't really like to oc due to lack of cooling for these phones, and they seem to run best if not too over done. been using deadline for a governor though and find its far more stable and efficient (great battery/performance) than cfq, so that's my only other recommendation for cymbaline.

Actually that is an I/O scheduler not a governor.

My bad, tis what I meant. But thnks for posting the clarification, the last thing i'd want to do is steer anyone in the wrong direction.

Scott's CleanKernel v. IMO's leanKernel

IMO updated his TouchWiz kernel yesterday. Up until today I was using Scott's CleanKernel. Both are amazing kernels in my eyes. Both kernels are undervolted and overclocked. I had no issues with CleanKernel at all. I always seems to have bad battery life on the leanKernel until I flashed the updated .4 version this morning. Battery life seems much better compared to any leanKernel before the update. When running CleanKernel, I got a quadrant score of 4980. With leanKernel 0.4 I got 5160, both at stock 1.5GHz. I just want to see if others have noticed what I have between these two kernels.

You forgot that both are released in the Development section. A place where this thread does NOT belong...

Just so you know in the future,
if your not a developer its always safe to open up new threads in the Q and A section. (At least that's my rule for myself.. it saves you from the "I'm having a bad day so I will take it out on this guy" post)

Now that this has been moved can we get back on topic? What is yalls experience with these two kernels?
Sent from my SCH-I535 using xda app-developers app

personally i like leankernal because of how light and simple it is. no unneccesary weight and battery life is great.

Clean kernel is closer to stock than imos kernel which is kinda good and bad. The more you modify the kernel the more chance you'll have of breaking something but you also have the posabilty of making it way better if done right and everything comes out ok.
I would expect clean kernel to be more stable, less battery efficient, and a little slower overall. Where imos kernel could vary drastically with each update due to more major things being edited or changed. Right now imos beta. 4 has pretty good battery life over stock and is stable.
Personally I try the more modified stuff first and if I don't feel it pays off I move to something more stable or closer to stock until an update is released or problem addressed. Just my. 02

Clean Kernel is under volt by default for a given frequency. That is why the battery life is better. If you are looking for both performance and battery life, you should over clock Clean Kernel frequency to 1.89 (default is 1.5) max and min should be 400 range. GPU in Clean Kernel is also over clocked. "stable" is the key word to differentiate between the two. I would think that Clean Kernel is the most stable kernel of all. For speed they should be the same, for bells and whistles, Lean kernel would be your choice. To sum up, Clean Kernel give you both world, stable, performance and battery life... unless you want something else beside those 3.

So you're a cleankernel guy? I definitely agree with you about this being all three things. So as far as the GPU being overclocked, why does lean kernel .4 perform better in games

Like I have mentioned, if you aiming for gaming performance then you better to use lean, but then your battery life wouldn't be too good. Most of people just want a fast stable phone and a good battery life for daily use, then Clean will be a better choice. The reason it's stable because no tweaks to it except for OC/UV. Have you tried to play game with Clean over clocked to 1.89?

Actually I never thought of overclocking and playing the game until now. I guess Im just used to being at stock. But I will give it a try and see how that works. But what your saying definitely makes sense and should clear some things up. Performace + battery life = cleankernel. PERFORMANCE + PERFORMANCE = leankernel. Although the battery life on leankernel has dramatically been improved.

Haha.. you got it...almost.. Performance+battery life+stable=Clean. Super perfornance -less battery life - 10% stable=Lean kernel. Good luck bro.

ok I just setup an app profile in setcpu. so now everytime im in my game, its overclocked. When im using it normally, its at stock speed. With the screen off, its at min 190 and max 452. so far so good!

.5 is up now with more fixes.

Thanks for the heads up! More battery drain fixes. Although it says in order to revert back to stock we have to flash a ROM with a kernel. Would a nan backup work? Anyone tests the kernel yet

What are you overclocked to?

I guess you can consider this thread part survey and part for my knowledge so I know how far I can push this phone. I am at 1728MHz max with the interactive governor and cfq scheduler. Not sure if I'm going to do any undervolting, I can get through the day with about 40% remaining, and I have profiles set up for low battery and such. I am running CM10 with the 747 (I think that's what its called..) kernel and can push it to 2.1GHz. Is it stable at that high of a clockspeed? I can assume it turns your pretty Galaxy S3 into a convenient portable stove
By the way, sorry if this is the wrong section.

It really depends on your phone, I had mine at 2100 and it was stable. However it can very I had,a, Droid charge that ran the 1440 no problem, had it replaced and the new one could go above 1300 without hot boots. Some phones just hold up better

Stock. I've had it clocked to 1.9. But can't tell a difference with real day to day function except for worse battery drain and phone hotter.
Sent from a SYNERGIZED GalaxySIII

I have run the KT747 AOSP kernel at 2.1 ghz for a day or more and had no noticeable increase in heat, or decrease in battery life. (lulzactive or smartass v2 with either cfq or sio scheduler, no voltage changes in KT tweaker) I also saw very little or no gain in real world performance increase, and the benchmarking apps seemed to back that up. Typically run mine at 1.809 currently. Every phone cpu is different in terms of top speed, and voltage settings. Best thing to do, is to test them and see what works best for you. These 2 links, courtesy of the Ktoonez thread, provide some great info on kernel governor and scheduler settings. Given the number of options in KT Tweaker, these helped me a great deal in terms of making changes.

I've tried 1998MHz and as you said, it didn't yield much. I think I screwed something up, because now oc settings refuse to stick (resets itself to 1512) and short/long benches are not as great.

Lightning Zap! Kernel feedback

Post here for your feedback on what you would like to see in the future for the Lightning Zap! kernel.
I want to know what are the most widely used governors, io-schedulers and over/under clock voltages.
I'll post some of my ideas here in a bit to get things rolling

Does it need any more? Quite the nice kernel, sir. Thank you again for all your help with getting mine up and running. You've been a valuable resource for me.

I'd love to see the badass governor added. Otherwise, it's handled everything I have thrown at it with ease.

smartass, sio and under volt were all I ever needed good sir. Your kernels always had the best deep sleep idle (1%)

Love the kernel sio/smartass combo is what I'm rocking...great battery life and super smooth keep up the great work. It makes it sooo hard to update to a new phone w the battery life I'm getting on my SR w this kernel and w Nibbles ROM. Any chance of you releasing a ROM of your own for the SR. I thought I read somewhere if you found the time you would cook something up for us...definitely would love that. Either way thanks for your hard work and time you put in for SR community we have greatly benefited from you

Everything seems to be running great no problems at all. I have heard a little about the RoW scheduler any chance this could be included in future builds?

Running ur latest kernel on this settings: i/o scheduler-noop,interactive governor,OC to 1677mhz and voltage all -50...I get really good battery life and great performance with this settings.

True. But I'm not sure if any of them are necessary for a properly functioning kernel. I know I can get rid of most of them for sure. But not sure about the governor tweaks

Day 2 on this kernel with Gs2usr's PACman rom. I'm on your recommended lionheart / noop, underclocked to 1026, and undervolted -50 across the board. So far I've gained 10% more battery life over the previous version on stock setup. It's been great so far man, thanks for showing up and providing the awesome kernel when we needed one so badly for the Skyrocket. You have been a true asset to the community since you've been here.

You can remove all the init.d scripts, but they are still part of the Lightning Zap! Project that are necessary for making this kernel what it is... beside, removing the scripts wouldn't make the size of the kernel much smaller, just shrink it a few kb...

Depends on the version, I believe the T11 base was built after October 14th so it should work. Just run a nandroid backup and try it. Worst that can happen is that it won't boot.

Slightly under clocked, noop i/o, interactive. Undervolted 100 across the board. Also running v6 script by zeppelinrox, along with seeder. Vincom superlite v8 with the LZ kernel. Awesome battery life. Thanks for all you do.

Hey u want to know what kind of governors ppl want so I like my battery life any gov that steps up fairly slow and drop quickly I love lulactive but if I remember right it doesn't play nice with our CPU. So anything that has good battery life.

Can faster CPU chips get away with lower volts?

I guess my title says it all. I can get away with like 750 maybe at the two lowest volts for ktoonz but 775 for sure and pretty gradually work up to about 1150 at 1512 and the lowest I can take 1890 is about 1260...i guess that's some background info..
Side question, can undervolting create lag? One kernel I used with similar voltage to what I used with ktoonz lagged like crazy but ended up being okay later, kind of strange actually. I know it causes reboots but never experienced lag, extreme lag like it would take like 5 seconds to respond..
Meh, ktoonz finally got around to catering to 4.3 and I'm back to sub 800 without lag...k I'm done rambling. I guess all that needs to be said is yes or no.
Thanks

If ur lagging while undervolting that means you are undervolted to low. Basically the CPU isn't getting enough power. Just increase +25 or +50 across the board should fix lag

That was an isolated event. I tried the same volts later with the same kernel w/o lag.
But judging by your response faster CPUs can run on lower volts?

I'm confused by your question. Run on lower volts compared to what? Any CPU can be undervolted. Remember each CPU is different and some will undervolted farther than others. Are you asking if a quad core will undervolt more the say the snapdragon pro 600?
